Abstract: An intra-amniotic loop catheter which allows direct access to a free floating segment of the umbilical cord for direct blood sampling. The loop catheter is formed of a flexible, resilient material with a distal, hook shaped end which may be straightened by an insertion or a removal tool but which returns to a hook shape when released. The hook is adapted to be oriented around a free floating section of the umbilical cord to allow insertion of a blood sampling needle into the umbilical cord through an opening in the proximal region of the hook.

Abstract: A tamper evidencing closure for a container, such as a bottle, in which a tamper indicator is completely separated from the closure upon removal of the closure. The tamper indicator is separated from the closure as the closure is removed from the container by contact between the tamper indicator and a finish on the container. The tamper indicator may form a product outlet in the closure when it is separated from the closure.

Abstract: A storage battery shrink wrap enclosure which includes foam pads to protect battery terminals and vent covers, and an outer form fitting shrink wrap covering. The enclosure allows batteries to be stacked, reduces potential for user contact with acid, and provides access to battery terminals for testing the battery charge level or boost charging the battery. The enclosure also includes a handle to facilitate battery handling and installation.

Abstract: A non woven fire blocking seat fabric particularly suited for aircraft applications is disclosed. The fabric is a nonwoven, multiplied flame resistant fabric comprised of at least two felted plies, each ply being further comprised of fibers selected from the group consisting of aramid fibers, polybenzimidazole fibers, and phenolic fibers, wherein the combined percentage by weight of said aramid and phenolic fibers is approximately 80% by weight of said felted ply with the aramid fibers being present in the range of about 10% to 60% and the phenolic fibers being present in the range of about 20% to 70%.; and the plies are united into a single fabric by fibers which are needled from the respective ply into the other ply. In the preferred fabric a stabilized woven scrim is positioned between the plies of the fabric. In the preferred fabric the scrim is of glass material.

Abstract: Apparatus for automatically stacking battery plates and separators is disclosed. Battery plates and separators elements are alternately and automatically combined on a conveyor belt to form sandwiches wherein a plurality of such sandwiches are later assembled for use in battery cells. Prior to combining the elements, the plates and separators are arranged in respective chutes for access by pivotably mounted vacuum pickup heads, which cycle between the chutes and the conveyor belt. The vacuum pickup heads capture the topmost elements in the chutes irrespective of the height at which the plates and separators may be stacked therein. In order to access the elements within the chutes, a jet sensor is provided with the pickup head that acts as a proximity detector. When vacuum is not being utilized for pickup purposes, it is utilized in an environmental mode where it is used to remove lead dust and particles around the stacking area.

Abstract: A fishing reel having shiftable concentrically-mounted gears engageable with each other via respective gear core members, with one core member of one gear having at least one perpendicular projection which is receivable by at least one well disposed in the core member of the other gear to thereby accomplish engagement of the two gears.

Abstract: A conveyor belt such as a paper-making fabric, said belt being made of spirals (2, 3) assembled together by rods (5) or by imbrication. With a view to reducing the permeability or to changing the surface condition, it has a generally flat member (7) which is inserted inside the spirals (2, 3) so as to completely or partially fill the spaces between or inside the spirals.

Abstract: A stainproof, flame-resistant composite sheet material including at least one silicone polymer layer containing a silicon resin or rubber and optionally a flame-resistant inorganic filler and at least one stainproof surface layer containing at least one synthetic thermoplastic stain-resistant, weathering-resistant polymeric material, the silicone polymer layer and the stainproof surface layer being bonded optionally through an adhesive material, a cold plasma or corona discharge-modified surface portion of the silicone polymer layer or a cold plasma or corona discharge-modified and graft polymerization-modified surface portion of the silicone polymer layer.

Abstract: A novel tamper-evident closure assembly for a container, such as a bottle, which can incorporate one or more tamper indicators that are severed from the closure assembly when the cap is removed. The tamper indicator can be shaped as a disk or any other distinct shape, such as in the form of a proprietary mark. Additionally, a proprietary mark, such as a trademark, can be placed on the visible surface of the tamper indicator.

Abstract: A display frame for a sign, poster, or the like. The frame comprises a plurality of frame sections each comprising a rear structure, a front structure, and tensioned spring means. The rear structure has a cylindrically shaped portion and an opposing channel spaced therefrom, while the front structure comprises a forward panel portion and a semi-circularly shaped portion, and with the latter being rotatably mounted on the cylindrical portion of the rear structure to thereby permit movement of the front structure from an open to a closed position. A spring means is disposed between the channel and the cylindrical portion of the rear structure, with the end thereof adjacent the cylindrical portion being circularly shaped. Said end biases against the leading edge of the semi-circularly shaped portion of the front structure when said structure is in the closed position, and against the solid section of the semi-circular portion when the front structure is moved toward or maintained at the open position.

Abstract: Disclosed is a process for preparing a water-proof sheet by forming a polymer coating on both the surfaces of a fibrous substrate fabric. At first, the fibrous substrate fabric is treated with a water repellant, and both the surfaces are subjected to the low temperature plasma treatment or corona discharge treatment. Then, a polymer coating is formed on both the surfaces. According to this process, the peel strength of the polymer coating is improved and the water absorbing property is reduced substantially to zero. If an inorganic fiber substrate fabric is treated according to this process, the bending resistance is highly improved in the resulting water-proof sheet.

Abstract: The present invention is directed to a low bulk pin-type seam for use with the flat woven fabric. The preferred fabric is woven with continuous or monofilament yarns in the machine direction. The seam is formed by interconnecting loops constructed from the machine direction warp yarns. In constructing the seam loops, a portion of the fabric is made free of cross machine direction yarns and the warp yarns are selected out as either a loop forming yarn or as binder yarns. The fabric is then folded back upon itself in hem like fashion with the selected yarns being retained as loop forming yarns and the binder yarns being drawn back through the hem portion of the fabric to bind the hem and body portion of the fabric. If desired, a stitch pattern may be added to further secure the hem area.

Abstract: An anti-theft system for vehicles, such as trucks, which is operated by a self-contained hand held transmitter. The system is enabled by activating the vehicle's parking brake system. The transmitter transmits a predetermined signal that activates/deactivates any one of a plurality of manually selected security systems only after the anti-theft system verifies the predetermined signal. Typical security systems lock the parking brake system or interrupt the fuel supply of the vehicle.

Abstract: A vent cap for enclosing filler openings of a storage battery comprises a base terminating at a ring including a generally U-shaped channel and a cover, the periphery of which engages the channel of the base. The periphery of the cover is provided with an essentially planar face having a chamfered termination and a plurality of circumferentially spaced, secant-shaped portions formed therein. The inner and outer faces of the cover are provided with relieved portions adjacent to the secant-shaped portions formed in the cover's periphery. The secant-shaped portions formed in the periphery of the cover and the relieved portions formed in the inner and outer faces of the cover cooperate with the U-shaped channel to develop a series of apertures between the base and cover.
